    Same as you, my favorite for handling (actually hiding) errors is IFERROR, or IF(ISERROR) before Excel 2010

    Frankly, I have never encountered #NULL before, as I have never written a formula for intersection and I doubt how many regular users would do it in workplace.

    But as you requested, here's one formula that returns #NULL
    =sum(A1:B2 C3:D4)

  2. Great podcast and Excel error resource post Chandoo! I will share this.
    I created a video last year about using ERROR.TYPE function to distinguish between error types.

  3. The Stig says:

    #NULL is easy to recreate. Simply write any formula that requires addition, subtraction, multiplication, or division and leave out the operator.

    A1 = 1
    A2 = 1

    =A1+A2 = 2
    =A1 A2 = #NULL

    Off to the races.
